The Complete Guide to Prostatic Artery Embolization (PAE)
Everything You Need to Know Before Making a Decision About Your Enlarged Prostate Treatment
If your prostate has been making your life miserable — the constant trips to the bathroom, the weak stream, the midnight wake-ups, the feeling that you can never fully empty — and you have been told your options are medication or surgery, this guide is for you.
Prostatic artery embolization is a minimally invasive outpatient procedure that shrinks the enlarged prostate by reducing its blood supply — without surgery, without general anesthesia, and without anything ever being inserted through the penis. It has been performed on tens of thousands of men worldwide, is supported by six randomized controlled trials and over twenty prospective studies, and is FDA recognized since 2018.
This guide covers everything: how PAE works, who is a good candidate, what the procedure actually feels like, how it compares to TURP and other surgical options, what recovery really looks like (day by day), success rates and long-term durability, cost and insurance coverage, and answers to the twenty most common questions we hear from patients.

WHAT IS PAE AND HOW DOES IT WORK?
Benign prostatic hyperplasia — BPH — is the medical term for an enlarged prostate. As men age, the prostate gland grows larger and compresses the urethra (the tube that carries urine out of the body), causing the frustrating symptoms you know all too well: frequent urination, urgency, weak stream, difficulty starting, incomplete emptying, and nighttime bathroom trips that destroy your sleep.
Prostatic artery embolization works by cutting off the blood supply that feeds this overgrown tissue. Without adequate blood flow, the enlarged prostate tissue gradually shrinks — typically by 20 to 40 percent over three to six months — relieving the compression on the urethra and restoring normal urinary function.
The procedure is performed by an interventional radiologist — a physician who specializes in using real-time imaging to guide instruments inside the body through tiny punctures, without surgical incisions. Here is how it works:
Dr. Bourgeois makes a small puncture — about the size of a pencil lead — in the wrist or groin. Through this puncture, a thin catheter (tube) is threaded into the arterial system and navigated using real-time X-ray guidance (fluoroscopy) to the tiny arteries that supply blood to the prostate. Once positioned, microscopic FDA-approved beads are injected through the catheter into these arteries. The beads lodge in the small blood vessels, blocking blood flow to the enlarged prostate tissue. This is repeated on both sides.
With its blood supply reduced, the enlarged prostate tissue gradually softens, shrinks, and decompresses the urethra. Symptom improvement typically begins within two to four weeks, with maximum benefit reached by three to six months. The prostate continues shrinking for up to twelve months after the procedure.
WHO IS A GOOD CANDIDATE FOR PAE?
PAE is appropriate for a wide range of men with symptomatic BPH. The best candidates typically include:
Men with moderate to severe BPH symptoms: If your International Prostate Symptom Score (IPSS) is above 13 — meaning your symptoms meaningfully affect your quality of life — you are likely a candidate. Symptoms include frequent urination (especially at night), urgency, weak or intermittent stream, straining, and the feeling of incomplete emptying.
Men whose medications are no longer working: BPH is progressive. Alpha-blockers like tamsulosin (Flomax) and 5-alpha reductase inhibitors like finasteride often provide relief initially, but 50 percent of men on these medications need treatment escalation within five years as the prostate continues growing. If your medications have stopped providing adequate relief or their side effects — dizziness, fatigue, sexual changes — have become unacceptable, PAE offers a way to address the underlying problem rather than managing symptoms.
Men who want to preserve sexual function: This is the number one reason patients seek PAE. TURP surgery causes retrograde ejaculation (dry orgasm) in 62 to 75 percent of men and carries a small but real risk of erectile dysfunction. PAE carries zero percent risk of new erectile dysfunction in large clinical studies, and 60 percent of men actually report improved erectile function after the procedure. Retrograde ejaculation rates with PAE range from 0 to 24 percent — dramatically lower than any surgical alternative.
Men with very large prostates: PAE has no upper prostate size limit. It works for prostates over 80 grams, over 100 grams, and even over 200 grams — sizes where UroLift (limited to 70-100 grams), Rezūm (limited to 80 cubic centimeters), and standard TURP (limited to approximately 80 grams) cannot be performed. For very large prostates, the only surgical alternatives are HoLEP, Aquablation, or open prostatectomy — all requiring general anesthesia and significantly longer recovery. PAE is actually technically easier with larger, more vascular prostates.
Men who want to avoid surgery or cannot tolerate general anesthesia: PAE is performed under conscious sedation (twilight sedation, similar to a colonoscopy) — not general anesthesia. This makes it accessible to men with heart disease, lung disease, or other conditions that increase surgical risk. There is no need for spinal or epidural anesthesia. Nothing is inserted through the penis.
Men with very large prostates: PAE has no upper prostate size limit. It works for prostates over 80 grams, over 100 grams, and even over 200 grams — sizes where UroLift (limited to 70-100 grams), Rezūm (limited to 80 cubic centimeters), and standard TURP (limited to approximately 80 grams) cannot be performed. For very large prostates, the only surgical alternatives are HoLEP, Aquablation, or open prostatectomy — all requiring general anesthesia and significantly longer recovery. PAE is actually technically easier with larger, more vascular prostates.
Men who cannot stop blood-thinning medications: Many BPH surgical options require stopping anticoagulants for days to weeks before the procedure, which poses risks for men with atrial fibrillation, mechanical heart valves, or recent stent placements. PAE can often be performed without stopping blood thinners or with only brief modifications.
PAE is generally not appropriate for men with prostate cancer (although it may be used in some research settings), men without BPH symptoms, or men with severe kidney disease that prevents the use of contrast dye. During your consultation, Dr. Bourgeois reviews your imaging, symptom scores, lab work, and medical history to determine whether PAE is the right approach for your specific situation.
THE PAE PROCEDURE — STEP BY STEP
Understanding exactly what happens before, during, and after the procedure eliminates the unknown — which is often what creates the most anxiety. Here is a detailed walkthrough of your PAE day:
Consultation and Treatment Planning
One to two weeks before your procedure, you complete pre-procedure blood work (kidney function, coagulation studies, PSA). You receive instructions about fasting (typically nothing to eat or drink after midnight), medication adjustments (blood thinners may need to be paused or modified), and what to bring. Arrange for someone to drive you home. You will likely receive a prescription for anti-inflammatory medication and possibly a short course of antibiotics to take starting the day before.
Arrival and Preparation:
You arrive at the hospital or outpatient center and check in at the day surgery unit. An IV is placed in your arm, monitoring equipment is attached, and you change into a hospital gown. The interventional radiology team reviews the plan with you, answers any last-minute questions, and confirms your allergies and medications.
Sedation and Access:
You receive conscious sedation through your IV — this puts you in a relaxed, drowsy state similar to what you would experience during a colonoscopy. You are breathing on your own and can respond to instructions, but you are comfortable and unlikely to remember details of the procedure. The access site — typically the wrist (radial artery) or groin (femoral artery) — is numbed with local anesthetic. A small puncture is made and a thin catheter is introduced into the artery. You may feel brief pressure but no sharp pain.
Catheter Navigation and Embolization:
Using real-time X-ray imaging (fluoroscopy) displayed on monitors, Dr. Bourgeois guides the catheter through the arterial system to the prostate arteries. A small amount of contrast dye is injected to create a detailed map of the blood vessels feeding the prostate. Once the target arteries are identified, microscopic beads (typically 100-300 micrometers, smaller than a grain of sand) are slowly injected through the catheter. The beads lodge in the tiny arteries, blocking blood flow to the enlarged prostate tissue. This process is performed on both the left and right prostate arteries for optimal results. You may feel a mild warmth or heaviness in the pelvic area during embolization — this is normal and temporary.
Completion and Bandage:
Once embolization is complete on both sides, the catheter is removed. If wrist access was used, a small pressure bandage is applied; if groin access was used, a closure device or manual pressure is applied. No stitches are needed. The entire procedure typically takes one to two hours, though complex anatomy may extend it to three hours.
Recovery and Discharge:
You are taken to the recovery area where you are monitored for two to four hours. Vital signs are checked regularly. You may experience mild pelvic discomfort, and some men feel increased urinary urgency within the first hours — both are normal signs that the embolization is taking effect. Once you are comfortable, eating and drinking, and your access site is stable, you are discharged home. Most patients leave the same day. A responsible adult must drive you home.
Key reassurance:
Nothing is inserted through the penis at any point during the procedure. There is no urethral catheter before, during, or after PAE in most cases — a major advantage over TURP (catheter for 1-3 days), Rezūm (catheter for 3-7 days), and open surgery.
PAE SUCCESS RATES AND LONG-TERM RESULTS
The clinical evidence for PAE is extensive, built on six randomized controlled trials, multiple large prospective studies, and over 20,000 procedures performed worldwide. Here are the numbers that matter:
Technical success — meaning the interventional radiologist successfully reaches and embolizes the prostate arteries — is achieved in 92 to 98 percent of procedures. The largest single study, published by Bhatia in 2024 with 1,075 patients, confirmed these rates.
Clinical success at one year — meaning significant, measurable symptom improvement — is approximately 90 percent. The average patient sees their International Prostate Symptom Score (IPSS) drop from approximately 23 (severe symptoms) to 6 or 7 (mild symptoms) — a reduction of roughly 16 points on a 35-point scale. Quality-of-life scores improve comparably.
Medium-term results at one to three years show clinical success of approximately 82 percent. Long-term data from the largest study with extended follow-up (Bilhim 2022, 1,072 patients with up to 10 years of data) shows 72 percent of patients maintaining clinical success at five years and 60 percent at ten years.
Prostate volume typically decreases by 20 to 40 percent over three to six months, with continued shrinkage for up to twelve months. This shrinkage is durable — the prostate does not regrow to its pre-treatment size.
Retreatment rates are approximately 20 percent at five years. This is higher than TURP (5-10 percent retreatment at five years), but PAE can be safely repeated, and importantly, PAE does not eliminate any future surgical options. Men who undergo PAE and later need additional treatment can still have TURP, HoLEP, or any other procedure — PAE burns no bridges.
When compared head-to-head with TURP in randomized trials, PAE achieves comparable IPSS improvement (PAE: 7-10 point reduction versus TURP: 10-13 point reduction) with dramatically fewer complications, shorter recovery, and superior sexual function preservation.

HOW PAE COMPARES TO OTHER BPH TREATMENTS
Most men considering PAE are weighing it against one or more alternatives. Here is a brief overview of how PAE stacks up. For a detailed comparison with specific data, visit our dedicated comparison page.
PAE vs. TURP:
TURP remains the surgical “gold standard” with slightly better long-term symptom scores and lower retreatment rates. However, PAE achieves comparable symptom improvement with dramatically faster recovery (1-3 days versus 2-6 weeks), no catheter requirement, no general anesthesia, and vastly superior sexual function preservation (0% new erectile dysfunction versus up to 10% with TURP; 0-24% retrograde ejaculation versus 62-75%). PAE costs approximately 20% less than TURP. For most men prioritizing quality of life and sexual function, PAE offers the better overall value. Detailed comparison
PAE vs. UroLift
UroLift uses permanent implants to mechanically hold the prostate open. It preserves sexual function well but is limited to prostates under 70-100 grams and cannot treat the median lobe. Five-year retreatment rates are 13.6%. PAE has no size limit and works on all prostate anatomies. Both are outpatient with fast recovery.
PAE vs. Rezūm
Rezūm uses steam injections to destroy prostate tissue. It preserves sexual function and can treat the median lobe, but is limited to prostates under 80 cubic centimeters and requires a urethral catheter for 3-7 days after the procedure. PAE requires no catheter and has no size limit.
PAE vs. Medications
Alpha-blockers (Flomax, tamsulosin) and 5-alpha reductase inhibitors (finasteride, dutasteride) provide moderate symptom relief but do not address the underlying prostate growth. PAE achieves 7-10 point IPSS improvement compared to 4-6 points for medications, and PAE actually shrinks the prostate rather than simply relaxing muscle or slowing growth. Many patients reduce or eliminate medications after PAE.
RECOVERY: WHAT THE FIRST WEEK REALLY LOOKS LIKE
We believe in honest recovery expectations. Most PAE patients recover quickly, but the first week is not symptom-free for everyone. Here is what to realistically expect:

RISKS AND SIDE EFFECTS
Every medical procedure carries some risk, and we believe you deserve complete transparency.
Serious adverse events are rare, occurring in 0.3 to 0.65 percent of patients in large clinical studies. These include non-target embolization (beads reaching tissues outside the prostate, which can cause temporary bladder irritation or, very rarely, rectal ischemia), access site complications (hematoma or pseudoaneurysm at the wrist or groin puncture), urinary tract infection (less than 1 percent), and contrast dye reactions.
Minor adverse events are more common and expected. Post-embolization syndrome affects 20 to 39 percent of patients during the first week: urinary urgency and frequency, mild pelvic discomfort, low-grade fever, fatigue, and blood-tinged urine. These symptoms are self-limiting and typically resolve within five to seven days with over-the-counter anti-inflammatories.
What PAE does NOT cause: There is zero incidence of urinary incontinence in large clinical studies. There is zero incidence of new erectile dysfunction. There is no need for blood transfusion. There is no surgical wound to heal.
For context, the overall complication profile of PAE is significantly more favorable than TURP, which carries risks of bleeding requiring transfusion (2-5 percent), urinary incontinence (1-3 percent), urethral stricture (4-7 percent), retrograde ejaculation (62-75 percent), and new erectile dysfunction (up to 10 percent).
COST AND INSURANCE COVERAGE
PAE is covered by most major insurance plans, including Medicare Part B, Blue Cross Blue Shield of Alabama, TRICARE, and most commercial insurers. Medicare pays 80 percent of the approved amount, with typical patient out-of-pocket costs ranging from $1,075 to $1,738 depending on your deductible and coinsurance.
A 2024 RSNA cost-effectiveness analysis found PAE to be the most cost-effective minimally invasive BPH treatment available, with three-year Medicare costs of approximately $2,934 compared to $6,038 for TURP. PAE costs roughly 20 percent less than surgical alternatives even before factoring in the reduced time off work and faster recovery.
For veterans and military families: TRICARE covers PAE when medically indicated. VA community care referrals may be available for PAE as an alternative to traveling to the Birmingham VA.

Frequently Asked Questions
Everything you need to know about prostatic artery embolization — procedure, recovery, costs, and results.
PAE is a minimally invasive outpatient procedure that shrinks an enlarged prostate by blocking its blood supply. A thin catheter is inserted through a small puncture in the wrist or groin and guided to the prostate arteries using real-time X-ray imaging. Microscopic FDA-approved beads are injected to block blood flow, causing the prostate to shrink 20 to 40 percent over three to six months. The procedure takes one to two hours under conscious sedation, and most patients go home the same day.
No. PAE is the only BPH treatment where patients consistently report improved sexual function. Large clinical studies show zero percent new erectile dysfunction after PAE, and 60 percent of men report improved erectile function. Retrograde ejaculation (dry orgasm) occurs in 0 to 24 percent of PAE patients compared to 62 to 75 percent after TURP. Preserving sexual function is the number one reason patients choose PAE over surgical alternatives.
Technical success is 92 to 98 percent. Clinical success at one year is approximately 90 percent, with average IPSS scores dropping from 23 (severe) to 6-7 (mild). At five years, 72 percent of patients maintain significant symptom relief, and at ten years, 60 percent. PAE achieves comparable quality-of-life improvement to TURP in randomized controlled trials.
Most men go home the same day and return to normal activities within one to three days. Return to work is typically within three to seven days. The first week may include increased urinary urgency and mild pelvic discomfort (post-PAE syndrome), which resolves within five to seven days. Compare this to TURP, which requires a two-to-six-week recovery. Symptom improvement begins at two to four weeks and continues for three to six months.
Yes. Medicare Part B covers PAE, paying 80 percent of the approved amount. Typical patient out-of-pocket costs are $1,075 to $1,738. Blue Cross Blue Shield of Alabama, TRICARE, UnitedHealthcare, Aetna, and most commercial plans cover PAE when medically indicated. Prior authorization is usually required, and our team handles this process.
PAE achieves comparable symptom improvement to TURP with dramatically faster recovery (1-3 days versus 2-6 weeks), no catheter requirement, no general anesthesia, superior sexual function preservation (0 percent new erectile dysfunction versus up to 10 percent; 0-24 percent retrograde ejaculation versus 62-75 percent), and approximately 20 percent lower cost. TURP has slightly better long-term retreatment rates (5-10 percent at 5 years versus 20 percent for PAE).
No. In most cases, no urethral catheter is required at any point. Nothing is inserted through the penis. Access is through a small puncture in the wrist or groin. This is a major advantage over TURP (catheter for 1-3 days after), Rezūm (catheter for 3-7 days), and open surgery. Some centers place a temporary reference catheter during the procedure only, which is removed before you go home.
Serious complications are rare, occurring in 0.3 to 0.65 percent of patients. The most common experience is post-PAE syndrome (20-39 percent of patients): temporary urinary urgency, mild pelvic discomfort, low-grade fever, and blood-tinged urine during the first week. This is self-limiting and managed with anti-inflammatories. PAE causes zero incontinence and zero new erectile dysfunction in large studies. The overall complication profile is significantly more favorable than TURP.
Yes. PAE has no upper prostate size limit and has been successfully performed on prostates exceeding 200 grams. It is actually technically easier on larger, more vascular prostates. In contrast, UroLift is limited to 70-100 grams, Rezūm to 80 cubic centimeters, and standard TURP to approximately 80 grams. For very large prostates, the only surgical alternatives are HoLEP, Aquablation, or open prostatectomy — all requiring general anesthesia and longer recovery.
BPH is progressive, and 50 percent of men on alpha-blockers need treatment escalation within five years. PAE addresses the underlying problem by physically shrinking the prostate, achieving 7-10 point IPSS improvement compared to 4-6 points for medications. Many patients reduce or eliminate BPH medications after PAE. If your Flomax, tamsulosin, or finasteride is no longer providing adequate relief, PAE may offer a more durable solution.
Most patients maintain significant relief for five to ten years. The largest long-term study (1,072 patients, Bilhim 2022) showed 72 percent clinical success at five years and 60 percent at ten years. Retreatment rates are approximately 20 percent at five years. If symptoms return, PAE can be safely repeated, and all surgical options remain available — PAE does not burn any bridges.
Not necessarily. PAE is performed by interventional radiologists, not urologists. Most urologists focus on the procedures they perform — TURP, HoLEP, UroLift, Rezūm — which are excellent treatments. Many patients discover PAE through their own research. No referral is typically needed to schedule a PAE consultation. PAE is FDA recognized and supported by six randomized controlled trials and over twenty prospective studies. Dr. Bourgeois is happy to coordinate with your existing urologist.
Post-PAE syndrome occurs in 20 to 39 percent of patients and includes increased urinary frequency and urgency, mild burning during urination, blood-tinged urine, low-grade fever, pelvic heaviness, and fatigue. This typically begins within the first 24 to 48 hours and resolves within five to seven days. It is not a complication — it is a normal response indicating the prostate tissue is reacting to the blocked blood supply. NSAIDs and a short course of antibiotics manage symptoms effectively.
Yes. PAE can be safely repeated if symptoms recur after initial treatment. Some patients who do not respond optimally to the first PAE had unilateral (one-sided) embolization — bilateral technique has better outcomes. Importantly, PAE does not prevent any future surgical options. If PAE is not sufficient, TURP, HoLEP, Aquablation, and all other treatments remain fully available. PAE is increasingly used as a pre-surgical step to reduce bleeding during subsequent procedures.
TRICARE covers therapeutic embolization when documented as safe, effective, and comparable to standard care — PAE qualifies. Prior authorization is typically required. For veterans, the VA may approve PAE through community care referrals, which would allow you to receive the procedure locally in Huntsville rather than traveling to the Birmingham VA Medical Center. Our office can assist with both TRICARE and VA authorization processes.
